If you are going to have a procedure done, you should going into it with all the information available. If a mother who has had a previous abortion gets pregnant with a child she wants, she will see the ultrasound and then she will know what a baby at 10 weeks gestation looks like, and she will have to deal with it then.
some women during there prenatal care, do not get their first ultrasound till they are 18-20 weeks depending upon the doctor and what not. and not all women get prenatal care, some only get it towards the end of their pregnancy. Some women have no clue what a baby looks like at 9 weeks or at 12 weeks etc. And they usually under estimate what development milestones are going on with the baby and what they have already accomplished.
I big surprise to me was learning from this thread that you get an ultrasound before an abortion. I did not know that. changes somewhat how I see the roles of mother/state/and doctors. No matter what an abortion is a traumatic experiance and I am not in anyone elses shoes but my own...therefore I can only speak for myself.
